"We're bringing a cathedral right off the strip in Las Vegas, it's called the Sphere and we are are going to make much mischief there. All we have been trying from the beginning was to break the fourth wall. This will hopefully take ourselves and our audience to the next level. We're choosing Achtung Baby because it's the place for such mischief. Because The Fly was always headed to Las Vegas." - Bono, March 2023
